U+2BDE "⯞" Black Diamond on Cross Unicode Character

U+2BDE "⯞" Black Diamond on Cross is a typographic symbol that combines a solid black diamond shape with a cross or plus sign intersecting its interior, creating a distinctive emblem often used in astrological contexts to represent the fixed star Algol, or in some alchemical and occult systems as a sign for sulfur or spiritual transformation. It belongs to the Miscellaneous Symbols and Arrows block in the Unicode standard, where it serves as a relatively rare but visually striking glyph for specialized notation in astronomy, metaphysics, and esoteric writing. The symbol’s design merges the diamond, which traditionally symbolizes durability or a precious substance, with the cross, a universal sign of balance, intersection, or celestial alignment, giving it a layered meaning that can vary depending on the field of use.
